THEY GET TO THE ISS. CONTROVERSIAL TWITTER COMMENTS ARE PUTTING GEORGE ZIMMERMAN'S BROTHER IN THE SPOTLIGHT. ROBERT ZIMMERMAN NOW APOLOGIZING FOR LIKENING TRAYVON MARTIN TO TWO GEORGIA TEENS ACCUSED OF MURDER. WESH 2'S AIXA DIAZ HAS ROBERT ZIMMERMAN'S RESPONSE TO THE CRITICISM. GEORGE ZIMMERMAN'S BROTHER ROBERT APPEARED ON CNNAST PIERS MORGAN TO APOLOGIZE FOR THIS PICTURE AND OTHER COMMENTS HE TWEETED. THE PHOTO SHOWS TRAYVON MARTIN ON THE RIGHT AND 17-YEAR-OLD MURDER SUSPECT ELKINS ON THE LEFT. BOTH BOYS ARE MAKING OBSCENE GESTURES. THE CAPTION READS: A PICTURE SPEAK AS THOUSAND WORDS. ANY QUESTIONS? ELKINS IS ONE OF TWO TEENAGERS ACCUSED OF SHOOTING AND KILLING A ONE-YEAR-OLD CHILD IN A STROLLER LAST WEEK IN GEORGIA. ZIMMERMAN ALSO TWEETED: LIBERAL MEDIA SHOULD ASK IF WHAT THESE TWO BLACK TEENS DID TO A WOMAN IS THE REASON PEOPLE THINK BLACKS MIGHT BE RISKY. IT SEEMS TO ME WHAT YOU WERE SAYING WAS THIS IS WHY YOUNG BLACKS ARE RISKY. IN OTHER WORDS, THAT IS WHY MY BROTHER GEORGE DID WHAT HE DID TO TRAYVON MARTIN. CERTAINLY THAT'S ONE WAY TO READ IT. AND THAT SEEMS TO BE THE WAY THAT A LOT OF PEOPLE HAVE INTERPRETED IT. AND I DON'T THINK TWITTER IS THE PLACE TO MAKE POINTS ABOUT WHAT YOU RECALL A YEAR AGO. BECAUSE THE RECOLLECTIONS THAT I HAVE OR THAT WE HAVE AS A FAMILY SPECIFICALLY ARE VERY DIFFERENT THAN WHAT CAN BE PORTRAYED IN 140 CHARACTERS. NOW I REALIZE THOSE WERE CONTROVERSIAL AND OFFENSIVE AND I DID PUBICALLY APOLOGIZE FOR THEM. I DON'T THINK IT WAS THE RIGHT THING TO DO THAT WAY. WESH 2 VIEWERS ARE SOUNDING OFF ON FACEBOOK. GEORGE ZIMMERMAN'S DEFENSE ATTORNEY MARK O'MARA ALSO RESPONDED. HE SAYS COMPARING TRAYVON MARTIN TO A MURDER SUSPECT JUST BECAUSE THEY'RE BOTH BLACK AND SHOWING
